Flor de Pascua. Poinsetia. Euphorbia pulcherrima

Euphorbia is a genus of plants belonging to the family Euphorbiaceae. Consisting of 2008 species, Euphorbia is one of the most diverse genera in the plant kingdom, exceeded possibly only by Senecio.^{[citation needed]} Members of the family and genus are sometimes referred to as Spurges. Euphorbia antiquorum is the type species for the genus Euphorbia; it was described by Carl Linnaeus in 1753 in Species Plantarum. The genus is primarily found in the tropical and subtropical regions of Africa and the Americas, but also in temperate zones worldwide. Succulent species originate mostly from Africa, the Americas and Madagascar. There exists a wide range of insular species: on the Hawaiian Islands where spurges are collectively known as "akoko", and on the Canary Islands as "tabaibas".
